Eat any of those perch out of the Fox?
I know if you are far enough North, there is little to no effluent in the system, and the river is a bit more "natural" (for a lack of a better word) lol.
I know I can tell a difference between Northern WI and Southern Wisconsin perch/crappie/bluegill. However, lake fish taste better to me than river fish, so maybe the same rules would apply in Illinois.
Killer video regardless, love the background music too.
